UNITED STATES PATENT 'OFFICEQ CHARLES KELLEY, OF TORONTO, CANADA.

COMBINED AIR-TRAP AND SEAT FOR PRlVY-VAULTS.

SPECIFICATION forming part of Letters Patent No. 465,862, dated December29, 1891.

Application filed April 2, 1891. Serial No. 387,403- (No model.) I

To all whom it may concern.-

Be it known that 1, CHARLES KELLEY, a subject of the Queen of GreatBritain, residing at Toronto, in the Province of Ontario and Dominion ofCanada, have invented certain new and useful Improvements in a CombinedAir-Trap and Seat for Privy-Vaults; and I do declare the following to bea full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of thisspecification.

This invention relates to certain new and useful improvements inprivies; and it relates more particularly to that class of privies whichare adapted for use in country towns and in other localities in whichfrom lack of proper sewerage connections the use of a cesspool or vaultis necessitated.

The invention has forits object to provide a privy of the characterdescribed with attachments whereby the excrementhole in the seat will beautomatically closed, except when in actual use.

'The invention has for its further object to provide an inlet-pipe forventilating purposes, the said pipe having an enlarged open end upon theoutside of the building and leading directly into the basin beneath theprivy-seat, the inner end of the said pipe being provided with a trap soarranged and connected with the seat-operating mechanism as to cause thetrap to be automatically opened simultaneously with the closing of theopeningin the privy seat and again closed when the excrement-hole in theseat shall have been opened.

Finally, the invention has for its object to generally improve upon theconstruction of outside privy-vaults and. their connections, whereby aperfect system of air ventilation will be at all times maintained whenthe privy is not in actual use and in which the escape of gases andoffensive odors into the building will be nevented.

The invention is clearly illustrated in the accompanying drawings,which, with the letters of reference marked thereon, form a part of thisspecification, like letters of reference indicating like partsthroughout the several views, and in which drawings- Figure 1 is aperspective view of a privy constructed in accordance with myinvention.Fig. 2 is acentral transverse vertical section of the same. Fig. 3 is acentral vertical longitudinal section through the basin.

Reference now being had to the details of the drawings by letter, Arepresents thebowl or basin, which is in all respects similar to thebasins which are now in common use, ex-

cepting that its rear wall is vertical, as shown at A. The bench orseat-support B may be of an ysuitable or desired construction, in thepresentinstance consisting of the uprights B", cornice-strips 1-3 andtop 13*, which is pro vided with the usual excrement-hole O.

The seat proper D is hinged at its rear edge to the strip E, and. in thedrawings I have shown strips E secured to the top of the stand andextending from the front to the rear of the same along the side edges ofthe seat, though this'construction is notmaterial, and itis at onceevident that these strips both at the rear and side edges of the seatmay be omitted when desired, and the rear edge of the seat in that eventmay be hinged directly to the top of the stand.

F is a crank-shaft, which is journaled within suitable bearings upon theunder face of the stand-top and extends transversely across the basinfrom front to rear at one side of and adjacent to the excrement-hole O.This shaft is provided at a point adjacent to its front end with a crankF, and to this crank is loosely or pivotally attached the vertical shaftG, the upper end of which shaft is passed loosely through an openingformed for its passage in the stand-top and bears against the under faceof the front edge of the hinged cover D. The lower end of the said shaftG is pivotally attached to the rear edge of the foot-board H, the frontedge of the said board being hinged either to the floor or to the frontedges of the foot of the standards or legs B, as shown. A short distancebelow the point at which the shaft Gis attached to the crankshaft l? aledge I is provided, through which the shaft passes, and sleeved uponthe shaft, with one of its ends bearing against the ledge I and itsopposite end bearing against the point of attachment of the said shaftto the crank F, is a spiral spring I. It will be seen that by thisconstruction when a weight is applied to the seat D the shaft G will bedepressed against the tension of the spring I and that this depressionof the shaft will serve to rotate the crank-shaft F, and it will also beobserved that the same result will be obtained by the depression of thefootboard H.

J is a sheet-metal plate, which at one of its side edges is secured tothe shaft F and-is adapted, when the said shaft is rotated by thedepression of either the seat D or the footboard II, to be thrown downso as to occupy a vertical position, as indicated in dotted lines inFig. 2 of the drawings, and upon release of the pressure to be returnedby the rotation of the shaft to its normal position, covering theeXcre1nent-hole,as shown in full lines in said figure of the drawings.

At the point at which the shaft F passes through the rear wall of thebasin Ait is provided with an arm F to the free end of which is pivotedthe end of a shaft F which is loosely sleeved within keepers f upon therear wall of the basin.

K is an air-inlet pipe provided at its outer end with an enlarged orflaring opening K upon the outside of the building and at its inner endcommunicating with the interior of the basin through an opening formedin its rear vertical wall.

The shaft F is provided with a shutter F of heavy sheet metal, said diskor shutter being secured at one of its edges to the shaft andadapted,when the shaft is moved by the rotation of the crank-shaft F, tobe moved across the opening K and removed therefrom upon occasion of areverse movement of the shaft F. In practice I so adjust the arm F as tocause the same to move the shaft F so as to close the opening Ksimultaneously with the opening of the excrement-hole in the seat by theturning down of the trap J, and in turn the same will be opened when thesaid trap is closed by the return movement of the crank-shaft occasionedby the release of pressure upon either the seat or foot-board. A pipe M,communicating with the basin and leading to the open air without thebuilding,

resses serves to insure an outlet for the gases and foul air, and aconstant and free current of air will thus at all times be maintainedwhen the trap is closed.

In order to prevent the possible escape of gases or air into the privythrough the spaces which mayintervene around the edges of the trap J, Iprovide a felt strip or pad N, which surrounds the excrement-hole uponthe under face of the stand-top B. This pad I keep moistened withcarbolic acid or with some other disinfectant suited to the purpose.

Having thus described my invention, what I claim to be new, and desireto secure by Letters Patent, is-

1. In a privy, the combination, with the basinhaving an air-inlet,valves adapted to control the excrement-hole and air-inlet,respectively, and-mechanism arranged to operate the said valvessimultaneously by a depression of the seat, substantially as and for thepurpose described.

2. The combinatiomwith the basin, the airinlet thereto, the seat, valvescontrolling the excrement-hole in the seat and the air-inlet,respectively, the foot-board hinged as described, and connectionsbetween the foot. board and valves, whereby the said valves may beactuated simultaneously by the depression of the foot-board,substantially as and for the purpose specified.

3. In a privy, a basin having an air-inlet, a seat having anexcrement-hole therein and. hinged at one of its edges, as described, acrank-shaft beneath the seat, valves controlling the air-inlet andexcrement-hole, respectively, and connected with the crank-shaft, afoot-board, and a shaft pivotally attached to the crank-shaft andextending from the footboard to the seat and adapted,when moved by thedepression of either the seat or foot-board, to rotate the crankshaftand to open the one and close the other of the respective valves connected therewith simultaneously, substan- 5 tially as and for thepurpose described.

In testimony whereof I affix my signature in presence of two witnesses.I
